Regarding what I have said, about the "non-Riemannian nature of perceptual color space" being known for decades, I have found an earlier paper with the same authors as the paper discussed here:
"Furthermore, human color perception is also non-Riemannian, due to the principle called diminishing returns [9]"
where the paper referenced as [9] is from 1968:
"D. B. Judd. Ideal color space: Curvature of color space and its implications for industrial color tolerances. Palette, 29(21-28):4–25, 1968."
Therefore the "non-Riemannian nature of perceptual color space" has been known at least from 1968, so whatever novelty is in the paper discussed here, this is not it, and the popular reporting about the paper is misleading.

There, the authors themselves have written:
